A syringe dispenser may include a plunger having an outer threading, a barrel adapted to contain liquid or semisolid fluid or any other material to be dispensed and to receive the plunger, the plunger being movably attached to the barrel, and a nut having an inner threading. The nut may at least partly enclose the plunger and the barrel, such that the inner threading of the nut engages with the outer threading of the plunger. A stand, an application plate, and a method of dispensing a controlled and measurable amount of liquid or semisolid fluid from a syringe dispenser are also disclosed.

1. A syringe dispenser, comprising a plunger having an outer threading;a barrel adapted to contain a material to be dispensed and to receive the plunger, the plunger being movably attached to the barrel; anda nut having an inner threading;wherein the nut at least partly encloses the plunger and the barrel, such that the inner threading of the nut engages with the outer threading of the plunger;wherein the nut is an openable snap-on nut being releasably attached to the plunger and the barrel, respectively;wherein the nut is of a unitary, one-piece construction with two half cylindrical parts connected by a hinge;wherein the half cylindrical parts have respective parting faces that are (1) exposed when the nut is opened about the hinge, and (2) unexposed in confrontation with each other when the nut is in a closed condition;wherein a first one of the parting faces has a ramped surface, such that a plane coincident with the ramped surface is spaced apart from a longitudinal center axis of the nut, anda blind hole provided closer to the longitudinal center axis than the ramped surface; andwherein a second one of the parting faces has a guide post that extends into the blind hole when he nut is in the dosed condition. 2. The syringe dispenser according to claim 1, wherein the barrel has a flange extending in a perpendicular direction to a longitudinal direction of the barrel. 3. The syringe dispenser according to claim 2, wherein the nut has a recess adapted to receive the flange of the barrel. 4. The syringe dispenser according to claim 1, wherein the outer threading extends in a longitudinal direction of the plunger. 5. The syringe dispenser according to claim 1, wherein the plunger has a plurality of side walls extending in a perpendicular direction to a longitudinal direction of the plunger. 6. The syringe dispenser according to claim 5, wherein a cross section of the plunger is cruciform. 7. The syringe dispenser according to claim 6, wherein the outer threading is arranged on an outer surface of each of the side walls of the plunger. 8. The syringe dispenser according to claim 1, wherein the inner threading extends in a longitudinal direction of the nut. 9. The syringe dispenser according to claim 1, wherein the plunger has a top having a marking corresponding to a marking of the nut. 10. The syringe dispenser according to claim 1, wherein a seal is attached to a bottom of the plunger for sealing the plunger against an inner wall surface of the barrel. 11. The syringe dispenser according to claim 1, further comprising a cap releasably attached to a tip of the syringe dispenser. 12. A method of dispensing a controlled and measurable amount of material from a syringe dispenser, the method comprising: providing a plunger having an outer threading;providing a barrel containing material;movably attaching the plunger to the barrel;releasably arranging an openable snap-on nut having an inner threading around the plunger and the barrel, respectively;wherein the nut is of a unitary, one-piece construction with two half cylindrical parts connected by a hinge;wherein the half cylindrical parts have respective parting faces that are (1) exposed when the nut is opened about the hinge, and (2) unexposed in confrontation with each other when the nut is in a closed condition;wherein a first one of the parting faces has a ramped surface, such that a plane coincident with the ramped surface is spaced apart from a longitudinal center axis of the nut, anda blind hole provided closer to the longitudinal center axis than the ramped surface;wherein a second one of the parting faces has a guide post that extends into the blind hole when the nut is in the closed condition;engaging the inner threading of the nut with the outer threading of the plunger; androtating the plunger relative to the nut and the barrel a distance, such that a controlled and measurable amount of material corresponding to the distance is dispensed from the syringe dispenser. 13. The method according to claim 12, wherein upon arranging the nut around the plunger and the barrel, the ramped surface slides across the second parting face of the nut.
